2 fluorescent plant/aquarium tubes in the back. I bought 1 in the household lighting department & it seems to give an "Amazon water" effect (on the L side). The other that I bought from the pet section has a sparkling blue effect (the R side). I don't know if 1 is better than the other for the plants but the fish seems to prefer the L side of the tank with the more natural lighting.

I've had tanks on & off since my teens. Since being disabled & on a strict budget, I've found that not having a TV is not missed at all because when I need to watch something I can enjoy the plants sway in the current & the fish happily swimming in the environment I've given them. I'm on the prowl for a nice piece of driftwood to add when I upgrade the substrate & get some Java Moss for it!
